Lysosome
Videos
A lysosome is a membrane-bound organelle that is found in all animal cells, and rarely in plant cells. There are normally hundreds of lysosomes in the cytosol, where they function as the cell's degrad
TEM views of various vesicular compartments. Lysosomes are denoted by "Ly". They are dyed dark due to their acidity; in the center of the top image, a Golgi Apparatus can be seen, distal from the cell membrane relative to the lysosome.
Cellular material is delivered to lysosomes in four different ways: (A) Macroautophagy, (B) Endosomal degradation, (C) Microautophagy and (D) Chaperone-mediated autophagy (CMA).

Endoplasmic reticulum

The endoplasmic reticulum is a part of a transportation system of the eukaryotic cell, and has many other important functions such as protein folding. The word endoplasmic means "within the cytoplasm"
